Set the detergent metering knob to
N
0 % (min)
Let the high-pressure cleaner
N
continue to run with the spray gun
open until no more detergent comes
out of the nozzle
see "Switching off the machine"

Transport
To prevent spillage of detergent during
transport:
Unscrew the cap with intake hose
N
from the detergent tank
Clip the intake hose into the groove
N
and engage the cap in the holder
Close the tank using the closed cap
N
Using detergent from a separate
container
Unscrew the cap with intake hose
N
from the detergent tank
Seal the filling opening of the
N
detergent tank with the closed cap
Screw the cap with intake hose onto
N
a separate detergent container
The cap has a standard thread and fits
all standard detergent containers.

Slide the intake hose as far as
N
possible into the detergent
container
Precisely calculating/setting the
detergent concentration
For a few detergents, the concentration
must be very precisely set. In this case,
measure the water flow and detergent
consumption.
Set the nozzle sleeve to low-
N
pressure operation – as described
above
Set the detergent metering knob to
N
"0 % (min)"
Hold the spray gun in a suitable
N
empty receptacle (> 20 l) and
actuate for exactly 1 minute
Measure the quantity of water "Q" in
N
the container
Fill 2 liters of detergent diluted as
N
directed into a suitable container
(with a scale of 0.1 l) – STIHL
recommends the use of genuine
STIHL detergents
Hold the intake hose in the
N
container
Set the detergent metering knob to
N
the desired concentration: 0 %
(min) to 5 % (max)
Hold the spray gun in a suitable
N
empty receptacle (> 20 l) and
actuate for exactly 1 minute
Read the detergent consumption
N
"QR" on the scale
Calculating the actual detergent
concentration:
RE 361, RE 361 PLUS, RE 461, RE 461 PLUS, RE 471 PLUS
QR
x V = concentration
Q
QR = Amount of consumed
–
detergent (in l/min)
Q = Water without detergent
–
(in l/min)
V = Predilution of detergent (in %)
–
If the actual concentration deviates from
the desired concentration, reset knob
and repeat measurement if necessary.
Calculating the predilution of the
detergent in %
If the predilution is not indicated as a
percentage, it can be calculated using
the following table:
Ratio
1:1 = 50 %
1:2 = 33.3 %
1:3 = 25 %
1:5 = 16.6 %
1:10 = 9 %
Example:
Calculation ratio of 1:2
A = 1
–
B = 2
–
A
x 100 = value in %
(A + B)
1
x 100 = 33.3 %
(1 + 2)
